In page Mouflon:

"

A mouflon was cloned successfully in early 2001 and lived at least seven months, making it the first clone of an endangered mammal to survive beyond infancy.[1][2][3] This demonstrated that a common species (in this case, a domestic sheep) can successfully become a surrogate for the birth of an exotic animal such as the mouflon. If cloning of the mouflon can proceed successfully, it has the potential to reduce strain on the number of living specimens.
